Brake Lights.....?

So my father and I noticed that I have no brake lights on my 62 UNI. I know the Governments didn't make brake lights mandatory til 1964.
So my question is: What do I need, and how do I install brake lights for my 62 UNI?

all slicks had brake lights
the factory sending unit is hydraulic and screws into the master cylinder.

I can't speak for the earlier trucks, but on my '66 the ignition key has to be "on" for the brake lights to work. This is unlike newer vehicles where the brake lights work whenever the brake pedal is pushed.
A bad brake light switch, or a bad turn signal switch can keep the brake lights from working.

Do the rear turn signals work?

when i had my 64 i had a heck of a problem keeping brake lights working. i could unscrew the brake light pressure switch and "bleed" it like you were bleeding the brakes and it would work again for a while. i ended up keeping the access covers off the back of the brake light housings so could see when they quit working and go out a "bleed" the switch again.
looking back, i probably had a slight leak in a brake line somewhere that was allowing air into the system. and once a bubble got up under the switch it acted like an insulator or pillow and wouldn't allow the brake pressure to activate the switch.
did that make any sense? lol

experience has lead me to check the electrical connection on the front of the master cylinder. Just a little corosion... no brake lights. Use steel wool and clean the connection and the lights work again.

Theres a good chance your brake light switch on the master cylinder is bad. If you jump across the teminals on the switch the brake lights should come on if the switch is bad.

Yes.
First, check to see if one of the wires to the switch is hot. (one of them will have power even with the ignition off.)
If that wire is hot and they don't come on after jumping across the posts on the switch, look for a bad ground at the light bulb socket [or a broken wire between the switch and the brake lights].
